China’s Material Control and Payment Infrastructure Challenge U.S. Beyond Tariff Theater
While Trump pursues trade deals, Beijing weaponizes rare earth controls and alternative payment systems to constrain Western technology and reduce dollar dependence.
China controls 90% of global rare earth processing and has systematically tightened export restrictions on critical minerals throughout 2025–2026, deploying a multi-layered economic warfare strategy that targets the physical inputs required for advanced manufacturing, defense systems, and AI infrastructure.
While the Trump administration continues pursuing tariff negotiations—with the overall average effective U.S. tariff rate standing at 13.7% as of February 2026—Beijing has shifted to a more sophisticated approach centered on supply chain weaponization and financial de-dollarization. China’s two-wave rare earth export control regime, coupled with operational BRICS payment infrastructure, represents a structural challenge that tariff concessions cannot resolve.
The Two-Wave Export Control Escalation
China implemented rare earth Export Controls in two distinct phases during 2025. The first wave in April 2025 targeted seven rare earth elements, while the second wave in October 2025 expanded restrictions to five additional elements and introduced extraterritorial provisions requiring licenses for foreign products containing trace amounts of Chinese-sourced materials at 0.1% concentration, according to China-Briefing.
The November 5, 2025 Trump-Xi agreement in Korea included a Chinese commitment to “effectively eliminate” export controls on Rare Earths and Critical Minerals. Beijing suspended the second-wave controls—but only until November 10, 2026, per the White House. The April 2025 first-wave restrictions remain fully active as of today.
Licensing approval rates tell the enforcement story. European firms face approval rates below 25%, while prices for controlled materials experienced sixfold spikes following implementation, data from Rare Earth Exchanges shows. Over 80% of European firms depend on Chinese supply chains for critical minerals, with rebuilding independent alternatives requiring 20–30 years—far exceeding current geopolitical windows.
“China is not weaponizing scarcity—it is weaponizing control. By tightening and loosening access in cycles, Beijing maintains pricing power, extracts strategic concessions, and slows the development of competing supply chains.”

Processing Dominance Over Mining
China’s strategic advantage lies in refining capacity rather than raw extraction. The country leads refining for 19 of 20 most important strategic minerals, with an average market share of 70% in critical mineral refining as of 2025, according to the International Energy Agency.
This processing chokepoint extends across materials essential for batteries, Semiconductors, and defense systems. China controls 99% of gallium production, 95% of magnesium, 83% of tungsten, and 79% of graphite, data from RealClearDefense indicates. In January 2026, Beijing placed 20 Japanese companies on an export “concern list” with enhanced dual-use controls, demonstrating willingness to extend restrictions beyond rare earths.
Even materials outside traditional rare earth categories face escalating controls. China elevated silver to strategic material status in 2025–2026, prompting Tesla CEO Elon Musk to warn in December 2025: “This is not good. Silver is needed in many industrial processes,” per CNBC.
Semiconductor Self-Sufficiency Accelerates
China’s domestic substitution program in semiconductors targets mature-node dominance rather than cutting-edge lithography. The country’s share of global mature-node semiconductor production is projected to grow from 31% in 2023 to 39% in 2027, while domestic wafer fab equipment market share rises to 25% in 2025 from 20% in 2024, analysis from Walter Scott & Partners shows.
Mature nodes—chips above 28 nanometers—power industrial equipment, automotive systems, power electronics, and defense platforms. By securing dominance in this segment, China reduces vulnerability to U.S. export controls on advanced lithography while building pricing power in components Western manufacturers cannot easily replace.
BRICS Payment Infrastructure Reduces Dollar Dependence
Parallel to material controls, China has accelerated construction of dollar-alternative payment systems. BRICS Pay entered operational phase in 2026, connecting central banks from China, India, Egypt, and the UAE with processing capacity of 20,000 messages per second, according to Watcher.Guru. Bloc members have shifted over 60% of mutual trade toward local currency settlements.
The Reserve Bank of India proposed linking Central Bank Digital Currencies of BRICS countries at a January 2026 meeting, with the framework set for the 2026 BRICS Summit agenda in India, per Modern Diplomacy. The mBridge platform—involving China, Hong Kong, Thailand, UAE, and Saudi Arabia—is already operational for cross-border settlements.
BRICS+ central banks accounted for more than 50% of all sovereign gold purchases globally between 2020 and 2024. Gold prices surged 60–70% during 2025, rising above $5,500 per ounce in early 2026—reflecting both inflation hedging and strategic reserve diversification away from dollar-denominated assets.
This dual-track strategy—controlling physical supply chains while building financial alternatives—insulates China from the primary leverage tools Washington has historically deployed: technology export bans and dollar-system exclusion. Beijing demonstrated this calculus in its November 2025 agreement with Trump, suspending only part of the rare earth regime while maintaining first-wave controls and setting a firm expiration date for concessions.
What to Watch
Licensing approval rates for rare earth exports remain the most immediate indicator of Chinese policy enforcement. Current sub-25% approval rates for European firms suggest Beijing maintains restrictive posture despite diplomatic commitments. Monitor whether approval rates rise as the November 10, 2026 suspension deadline approaches—a signal of potential extension or full reversal.
BRICS payment system adoption metrics will reveal whether operational infrastructure translates to sustained transactional volume. Current 60% local currency settlement among bloc members represents theoretical capacity; monthly transaction data and participant expansion beyond the initial four central banks will indicate whether the system achieves critical mass or remains a parallel niche network.
China’s domestic semiconductor production figures for mature nodes, due quarterly from industry associations, will show whether the 39% global market share projection by 2027 remains on track. Any acceleration in domestic wafer fab equipment market share above the projected 25% for 2025 would signal faster-than-expected technological substitution, reducing Beijing’s vulnerability to Western export controls.
The May 14–15, 2026 Trump-Xi summit in Beijing represents the next inflection point. Trump threatened 50% tariffs on China over alleged weapons shipments to Iran on April 13, 2026—demonstrating that trade negotiations remain subject to geopolitical disruptions beyond economic considerations. Watch for any explicit commitments on first-wave rare earth controls, which remain fully active despite November 2025 suspension of second-wave measures.
China’s material control and payment infrastructure represent a structural challenge that tariffs alone cannot resolve. By weaponizing supply chain chokepoints in rare earths, critical minerals, and mature-node semiconductors—while simultaneously building dollar-alternative payment systems—Beijing has constructed a multi-layered resilience strategy designed to sustain economic coercion regardless of bilateral trade outcomes. The November 2025 agreement suspending second-wave rare earth controls until November 2026 offers temporary tactical relief, but the underlying strategic posture remains: China controls the physical inputs that determine technological dominance, and no tariff concession can dislodge that advantage without decades-long investment in alternative processing capacity. As Washington pursues trade deals measured in tariff percentages, Beijing is reshaping the material and financial foundations of the global economy.
